Hello,

I am opening a QColorPicker dialog from another dialog opened with Qt::Dialog | Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint flags.

All it's well the color picker linux dialog opens above the original dialog, the problem is that after I select the color and close or cancel the color picker dialog ... the application blocks...if I debug it it seems the color picker dialog is blocked on a mutex somewhere in qt sources.

I have to mention the same code does only replicates on Linux, on MacOS or Windows versions iit works ok.
Also the QFontDialog opened from the same (modal) dialog opens and closes just fine.

Thank you.
